我有一個自定義的方法，我在紅寶石，我希望把我的Rails應用程序。我在哪裏添加了參數和數學的自定義導軌方法？
您可以在這裏測試一下：https://repl.it/Ezqr/20
def time_clock(hour, min)
...
end
我也有一個簡單的支架一個Rails應用程序。我跑將支架
rails g scaffold Timeclock hour_in:integer minutes_in:integer
我希望能夠把我的自定義time_clock方法到我的Rails應用程序，看看它在視圖中。但該方法去哪裏？或者至少我該如何將它實現到我的Rails應用程序中？它會進入控制器還是模型？...幫助！
我通過在我的視圖中使用此代碼得到了它的工作。有更好的做法嗎？
<div id="page_wrapper">

有沒有更好的方法來做到這一點？
您可以將此代碼查看xxx.html.erb
<div id="page_wrapper">
<p id="notice"><%= notice %></p>
<h1>Listing Timeclocks</h1>
<% @timeclocks.each do |timeclock| %>
<div class="timeclock_wrapper">
<p class="date">
Submitted <%= time_ago_in_words(timeclock.created_at) %> Ago
</p>
<%= minutes, fin_hour_with_30, fin_hour = min_hour_and_half_hour(timeclock) %>
<p> You are off at <strong><%= "#{fin_hour}:#{minutes}" %></strong> PM Without A lunch </p>
<p> You are off at <strong><%= "#{fin_hour_with_30}:#{minutes_with_30}" %></strong> PM With A 30 minute lunch </p>
<p> You are off at <strong><%= "#{fin_hour.to_i + 1}:#{minutes}" %></strong> PM With A 1 Hour lunch</p>
<p>Inserted Hour: <strong><%= timeclock.hour_in %></strong></p>
<% if timeclock.minutes_in < 10 %>
<p>Final Minutes: 0<%= timeclock.minutes_in %></p>
<p>Inserted Minutes 0<%= timeclock.minutes_in %></p>
<% else %>
<p>Final Minutes: <%= timeclock.minutes_in %></p>
<p>Inserted Minutes <%= timeclock.minutes_in %></p>
<% end %>
<button class="button"> <%= link_to 'Show', timeclock %></button>
<button class="button"> <%= link_to 'Edit', edit_timeclock_path(timeclock) %></button>
<button class="button"> <%= link_to 'Destroy', timeclock, method: :delete, data: { confirm: 'Are you sure?' } %></button>
</div>
<% end %>
<br>
<button class="button"><%= link_to 'New Timeclock', new_timeclock_path %></button>
</div>
而且可以使一個輔助方法，就像在helpers/application.rb
module ApplicationHelper
def min_hour_and_half_hour(timeclock)
minutes = timeclock.minutes_in % 60
fin_hour = (timeclock.hour_in + 8) - 12
if (57 <= minutes) && (minutes <= 59) || (0 <= minutes) && (minutes <= 2)
minutes = "00"
minutes_with_30 = "30"
fin_hour_with_30 = fin_hour
elsif (3 <= minutes) && (minutes <= 8 )
minutes = "06"
minutes_with_30 = "36"
fin_hour_with_30 = fin_hour
elsif (9 <= minutes) && (minutes <= 14)
minutes = "12"
minutes_with_30 = "42"
fin_hour_with_30 = fin_hour
elsif (15 <= minutes) && (minutes <= 20)
minutes = "18"
minutes_with_30 = "48"
fin_hour_with_30 = fin_hour
elsif (21 <= minutes) && (minutes <= 26)
minutes = "24"
minutes_with_30 = "54"
fin_hour_with_30 = fin_hour
elsif (27 <= minutes) && (minutes <= 32)
minutes = "30"
fin_hour_with_30 = fin_hour + 1
minutes_with_30 = "00"
fin_hour_with_30 = fin_hour + 1
elsif (33 <= minutes) && (minutes <= 38)
minutes = "36"
minutes_with_30 = "06"
fin_hour_with_30 = fin_hour + 1
elsif (39 <= minutes) && (minutes <= 44)
fin_hour_with_30 = fin_hour + 1
minutes = "42"
minutes_with_30 = "12"
elsif (45 <= minutes) && (minutes <= 50)
fin_hour_with_30 = fin_hour + 1
minutes = "48"
minutes_with_30 = "18"
elsif (51 <= minutes) && (minutes <= 56)
fin_hour_with_30 = fin_hour + 1
minutes = "54"
minutes_with_30 = "24"
else
minutes = min % 60
end
minutes, fin_hour_with_30, fin_hour
end
end
這將是位清晰，整齊碼。
你打算只在視圖中使用'time_clock'嗎？它取決於你想在哪裏使用它。 –
以及我想顯示方法中的返回值。該方法向上或向下舍入數字。這是我工作時間用來計時的人工時鐘。我想在視圖中顯示新的價值。 – Gcamara14
你有沒有嘗試把它放進一個幫手，並嘗試訪問你的看法中的一種方法？ –
